I am using IntelliJ IDEA. I am used to work with Maven multi-module projects in it in a way like follows:

1. Create a project.
2. Create modules, say, M1, M2, M0, and M00.
3. Setup all POMs etc → done.

Let's say module M00 is a public API of my project, which is also used internally by module M0, which itself is a common private part of my project which other modules depend on.

That is, M1 and M2 both depend on M0, while M0 also depends on M00, that is, in modules M1 and M2 I can use all the code from modules M0 and M00.

With Maven, this is all as simple as just creating the modules, writing code, and then simply compiling them (with proper POMs configured). With Gradle, however, I cannot access code (classes/methods/...) of one module from inside another.

The only solution I found is to build the aforementioned M00 module separately from everything and install it in my local Maven repository, then do the same for module M0, and then use both modules just like any other external dependencies in other/main modules (M1 and M2).

This means that I have to waste really much time doing that monotonous and boring work every time I make any changes to modules M0 or M00 (while with Maven, IntelliJ detects code from modules of the same project and uses it automatically, without making me always build and install the "dependencies" every time I make a change).

Is there any way to make this simpler ("Maven-like")? Because I don't really see any reasons to use Gradle for such a project otherwise since it only hardens and slows down the development.

P.S.: I am very new to Gradle
